Windows Vista gives your less performance on games because a video card's acceleration is used on the desktop. The desktop Aero is considered a 3D program. Not like Windows XP's User interface. Also the OS is bloated because Microsoft assumes that everyone is a pirate so those security features in their OS is not about protecting you...Its about protecting their profits, so everything gets slowed down on Vista...thanks to all the DRM, the registry and all the Processes loaded at once.
Once you optimize Vista by not using Aero and cutting down all of those processes, you can get a much higher framerate. Also, although Vista comes with Direct X 10. Its good to install DirectX9c because they have more comptability with DirectX7, 7a and 8...Where DeusEx is direct X 7.
If you are playing the multiplayer, It can run on OpenGL pretty well too. Good luck.
